Hi there!
This is my third topic but it's really important (I have a lot of work inside my computer)
I've installed Q4OS normally okay? Well, when I do apt update and apt upgrade, everything's okay, but then, when I restart my computer and boot it again, it appears the mistake.

Error: symbol Grub_is_lockdown not found
Grub rescue

This error appears if I install Q4OS as UEFI (32 bits picturing) but if I install it as Legacy(16 bits picturing) it doesn't make the mistake.

Most of people would say to install it as Legacy but I really don't like it. I observed that if I use grub-install /dev/sea, this installs Grub-efi-amd64 and I think this is the mistake that makes the mistake appears

Please Q4OS SUPPORT could you help me?? There is a post about this but the solution is not working … ost-115382

Please I have a lot of work there. If anyone can help me, it will be welcomed

Re: Grub-efi-amd64

You likely encountered the upstream Debian bug … bug=984760 , by the way marked as critical.
